Triaxial tests were employed to investigate palm-fiber-reinforced sand under consolidated drained conditions in this study. Sixteen series of triaxial carried out the properties sand. One pure was also for comparison. The deviator stress, stress path, shear strength, volume change, void ratio, and enhanced coefficient fiber-reinforced studied with different fiber lengths varying from 8 mm 20 co...

In this study, polyphenylsulfone (PPSU) hollow fiber membrane was fabricated via a wet spinning method with the addition of ethylene glycol (EG) in the range of 0-10 wt% as the additive. The EG was added to improve the membrane pore formation and interconnectivity for better membrane contactor performance in extracting and removing the free fatty acid (FFA) from crude palm oil (CPO). Four diffe...

The goal of this research is to investigate strategies increase the erosion resistance slope surface during early stages vegetation concrete construction, as well offer a scientific foundation for improving formulation. Simulated rainfall experiments were carried out at 2 different gradients (50° and 60°), intensities (60 120 mm·h−1), 4 treatments (CK-no additive, 0.4% P-polyacrylamide, 4% C-bi...

Fiber-reinforced soil is an excellent engineering material that has become a focus of research. Most studies on the conventional mechanical properties reinforced soil, such as its tensile, compressive, and shear strength, rarely study creep-related properties. However, when used backfill, creep effect should not be ignored. This explored characteristics mechanics in fiber-reinforcement mechanis...

In Southeast Asia, expansion of oil-palm agriculture, in combination with other industries (logging, fiber, and mega-dams), is transforming significant portions of the landscape threatening biodiversity, key ecosystem services, and human cultural diversity. While transformative answers to these multifaceted environmental issues seem daunting, the conservation biology literature provides a road ...

In this study, we have designed, fabricated, and characterized a miniaturized optical fiber-coupled terahertz (THz) endoscope system. The endoscopic system utilized a photoconductive generator and detector driven by a mode-locked Ti:sapphire laser. In reflection mode, the endoscope showed a high signal-to-noise ratio and a wide frequency spectrum similar to the conventional THz time-domain spec...

This thesis investigates the mechanisms underpinning pleasant touch, describes a pathway from peripheral nerve endings in the skin to the insular cortex, and relates these findings to the subjective hedonic experience of touch. In Paper I, the relationship between primary afferent encoding and perception of pleasantness was investigated by combining microneurography recordings from human mechan...
